Monster Manual
Innate Spellcasting. The hag’s innate spellcasting ability is Charisma (spell save DC 13). She can innately cast the following spells:
Tormenting the Weak. Although annis hags can easily tear a grown man apart, they love hunting children, preferring their flesh above all others. They use the flayed skin of such victims to make supple leather, and a hag's lair often shows the signs of this industry. Annis hags leave tokens of their cruelty at the edges of forests and other areas they claim. In this way, they provoke fear and paranoia in nearby villages and settlements. To an annis hag, nothing is sweeter than turning a vibrant community into a place paralyzed with terror, where folk never venture out at night, strangers are met with suspicion and anger, and parents warn their children to "be good, or the annis will get you." Child Corrupter. When an annis feels especially cruel, she disguises herself as a kindly-looking elderly woman, approaches a child in a remote place, and gives it an iron token that it can use to confide in her. Over time, "Granny" convinces the child that it's okay to have bad thoughts and do bad deeds--starting with breaking things or wandering outside without permission, then graduating to pushing someone down the stairs or setting a house on fire. Sooner or later, the child's family and community become terrified of the "bad seed" and must face the awful decision of whether the child should be punished or exiled. Tribe Mother. Much in the way that they befriend children in order to corrupt them, annis hags have a tendency for adopting a group of ogres, trolls, or other loutish creatures, ruling them through brute strength, verbal abuse, and superstition. Covens. An annis hag that is part of a coven (see the "Hag Covens" sidebar in the Monster Manual) has a challenge rating of 8 (3,900 XP).
Multiattack. The annis makes three attacks: one with her bite and two with her claws. Bite. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) piercing damage. Claw. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 15 (3d6 + 5) slashing damage. Crushing Hug. Melee Weapon Attack: +8 to hit, reach 5 ft., one target. Hit: 36 (9d6 + 5) bludgeoning damage, and the target is grappled (escape DC 15) if it is a Large or smaller creature. Until the grapple ends, the target takes 36 (9d6 + 5) bludgeoning damage at the start of each of the hag's turns. The hag can't make attacks while grappling a creature in this way.
